Application filed January 28, 1910. Serial No. 540,569.

To all te/tom. it may concern r Be it known that I, CHARLES W. Giuliani,

residing at Rome, in the county of Oneida,

State of New York, have invented certain new and useful Improvements in Can-Body- Forming Machines, of which the following is a specification.

This invention relates in general to machinery for handling and working sheet metal, and in particular to means for. forming can bodies and the like. One of the objects of the invention is to provide a unitary mechanism which Wlll automatically and efficiently :t'orm articles of the above type t'rom sheets of metal, the said machine including improved mecha nisms adapted to carry out each of the several steps contributingto such :t'orniation.

Another object is to provide particularly simple, durable and reliable means for carrying on each stage of the above named formation in proper succession, and preparing the article for the nextsucceeding step.

Other objects, more or less broad than those above stated, together with the ad wintages inherent, will be in part obvious and in part specifically adverted to in the course of the following detailed description of the elements, combinations, arrangements of parts, and applications of principles constituting my invention, and the scope of the application thereof will be indicated in the appended claims.

In the accompanying drawings, which are to be taken as a part of this specification, and inwliich I have; shown a merely preferred "form of embodiment of the invention and i of the various features ancillary thereto Figure l is a rear elevation of a machine embodying my improvements, the positions of some of the parts being indicated in Fig. 2 is a front elevation o'l V l the structure shown in Pig. 1, and (liselos ing some parts not shown in Fig. 1. Fig. I, is a top plan view (it the same, with the blank :t'eeding mechanism removed; Fig. 41-

Fig. 97 is a detail of the ex 'iansible horn 105 and complementary forming jaws, showing the horn contracted and the hooks of the blank inlerengaged; Fig. is a view similar to Fig. '27, showing the horn expanded and the hooks interlocked,- and showing also 110 is a detail, partly the relative position of the bumper; Fig. 29 is a view similar to 28, showing the horn and the bumper pressing the can body seam; Fig. 30 is a-detail of the two-part link included in the bumper drive; 31 is asection, partly in elevation, on the line 31- 31 of Fig. 30 Fig. is a the parts of the link shown in 30, disassembled; Fig. 33 is a detail of a member for regulating the compression spring be tween the parts of the link; Fig. 34- is a detail perspective of a bearing block coiiperative with the member shown in Fig 33 win the performance of the function of the latter; Fig. 35 is an elevation, partly in ection, of one of the notcher devices and its immediate'actuating connections;'l ig. 36 is asection on the line 86-436 of Fig. 85; Fig. 37 is a section on the line 31-33? of Fig. 35; Fig. 38 is a detail of one of the notchers prdper; an Fig. 39 is a partial, central, vertical section, part of which is taken along the lines ESQ- 39 of Fig. 2.

The reference letters and numerals herein used indicate, respectively, thcsame parts in the several figures of the drawings. The ar rows indicate, without further description, the directions of movement of'parts; and where single figures of the drawings are referred to in this specification, such refer ence is only intended ,to point out a figure in which the specific parts referred to are well shown, and other figures may show thesame parts.

In order to obtain a clear understanding of the nature of my invention, it may be premised that on account of the low selling price of the individual product of can form ing machines, it is essential that the amount of manual labor necessarily expended be small, and the rate of production high. To accomplish this object if have provided a machine, hereinafter described, which is entirely automatic in action,'and each distinct part of which performs its functions efliciently and prepares the article for the next succeeding step. In this machine it is of importance that the blanks be positively fed thereto singly, and that meansbe provided for progressing the sameihrough the machine at proper times during the various stages of its formation, and at all timesby edge engagement in the same generaldirect-ion. It has also been found highly to provide mechanism for automatically stopping the machine upon the happening of a given circumstance, as when two blanks simultaneously, oran excessively thick b ank, are prcsented to the machine.

Another desirable feature is the provision of means for maintaining the blanks flat upon the bed along which they are pro gressed, and means for maintaining the edges of the blankin proper alinement with f each other and or with the various blank perspective of desirable oa ers the latter being always accomplished by rear edge-engagement.

T have also provided other novel andad vantageous features, to which attention will be called in connection with the description of various parts of the machine.

Referring to the drawings, there is shown a frame comprising a base 1, from which rise side walls 2 and 8. A main shaft 4t has hearings in said side walls, and may be driven by a pulley et exteriorly of the ma chine frame.

5 indicates a secondary shaft, disposed transversely of shaft 4:, and driven therefrom by means of worm gearing 6 and 7 on the shafts at and 5, respectively, the env gagin, portions of. sa1d shafts being 1ncluded in a boxing 8, which. rises from and is preferably integral with the base 1, said boxing being provided with transversely disposed bearings for the two shafts respectively, as clearly shown'in Figs. 4 and 5, for instance. The shaft 5', through suitable connections, drives all of the moving parts of the machine, and the connections may be briefly indicated as follows :.9 is a standard at the front of the machine, preferably integral with the base 1, and formed with a bcaringll for the rear end of the shaft 5. A bracket 12 secured to base 1 carries spiral gear 14:, on a shaft 15, and gear 14 is driven by engagement with a corresponding gear 16 on the shaft 5. Shaft 15 has bearing in a sleeve '17 (see Fig. 5) and at its other end from the gear 1 f carries a sprocket-wheel 18, which drives, as by means of chain 19, the sprocket-wheel drive20 of a blank'supporting and feeding device 21. The rear end of shaft 5 also carries a crank pin 22,

which, through intermediate linkage hereafter described, operates 2 1 is a vertical sh ft havlngan end thrust bearing the horlzontal bearingll of the shaft 5, and said' shaft 24c revolves within a sleeve 25 connected to the bearing 11. Said. driven througlrbevel gears 26 and 27 thereon,

vertical shaft is and on the shaft 5, respecto actuate means for progressing tivelv as hereinafter blanks through the machine,

described. Forwardly of its length the shaft 5 is provided with a spiral gear 28, which engages a corresponding gear 29, carried on brackets 32 and 33 ex- I a shaft 31 between tending forwardly from boxing 8; the shaft '31 being arranged transversely of themachine frame, and having bearings in the side walls (see 5). The said shaft 31 drives, by means of eccentrics 3 T and 35, and intermediate connections, edging devices, herein v Shaft 31 also carries, ad jacent its bearing in the wall 2, a sprocket" 'wheel 36, which drives,

after described.

through chain 37, a

sprocket-wheel 38 on shaft 39'having end bearings in the side walls and an IIDJCGIIHLB-Y' a; horn expander.
